Nokia introduced four new multimedia-savvy phones, as well as a Beta version of its Nokia Maps 2.0 application. Handsets include a N95 successor the N96, which includes 16 GB of internal memory.

As it continues to push into the services side of mobile, Nokia’s Beta Maps 2.0 adds Walk, a pedestrian focused navigation component and an option to purchase multimedia guides that feature photos, videos and audio streams. The world’s largest handset maker also announced plans to bring a more mass-market version of its Maps application to Series 40-based phones during the first half of the year.

While Sony Ericsson announced its first Windows Mobile-based handset, Nokia says it does not have plans to do a Windows phone, though it does hope to launch a Series 60-based touchscreen platform in the second half of the year.

In more mobile services news from Nokia, the company said it was also in talks with social networking site Facebook. The handset vendor has said that it would like to improve the usability of the social networking site from its handsets.
